Abstract: A tip processing apparatus is equipped with a holder and a holder holding unit for extending the tip of the jacketed optical fiber comprising at least one optical fiber provided with a jacket, the holder holding the jacketed optical fiber in place. The apparatus also includes in a jacket removing unit for removing a desired length of the jacket, leaving the jacket on the tip of the jacketed optical fiber; a cleaning unit for cleaning the optical fiber exposed by the jacket removal carried out in the jacket removing unit; and a cutting unit for performing cut processing thereby to trim the optical fiber cleaned by the cleaning unit. A tip processing method comprises moving a portion of the jacket by a desired length while leaving a portion of the jacket on the tip, and all processing steps of the jacket removing, cleaning, and cutting of the optical fiber are performed on the optical fiber with the jacket portion left on the tip.

Abstract: An automatic optical measuring apparatus for optical fibers which is designed to automatically perform a series of steps from processing tips to optical measurement of a plurality of jacketed optical fibers each comprising at least one optical fiber provided with a jacket.

Abstract: An optical switch system used in a monitoring system for monitoring a large-scale optical transmission including a multiplicity of optical fibers, or like systems for switching optical transmission paths. The optical switch system comprises first and second optical switches. The first optical switch serves to optically connect one end face of a single first optical fiber selectively to one end face of any one of n second optical fibers. The second optical switch serves to optically connect end faces of n third optical fibers collectively and substantially synchronously to end faces of fourth optical fibers of a desired bundle selected from a plurality of optical fiber bundles each composed of substantially n optical fibers, the third optical fibers being optically connected at other end faces to other end faces of the second optical fibers.
